The effect of galanin gene polymorphism rs948854 on the severity of multiple sclerosis: A significant association with the age of onset.

Background: Data on genetic markers that determine the prognosis of multiple sclerosis (MS) is still limited. The association between galanin gene polymorphism rs948854 and prognosis of MS had been demonstrated earlier.

Objectives: To confirm earlier findings in a distinct from the previously studied cohort of patients, and to further characterized the rs948854 polymorphism as one of the candidates for the risk stratification in patients with MS.

Validation of the Russian version of the Fatigue Impact Scale and Fatigue Severity Scale in multiple sclerosis patients.

Background: Fatigue is a common complaint in patients with multiple sclerosis (MS), and its detection and monitoring are based on self-reported questionnaires. The objective of this study was to validate the Russian translation of the Fatigue Impact Scale (FIS) and the Fatigue Severity Scale (FSS) in MS patients and controls.

Methods: We included 85 MS patients and 250 age-, sex-, and body mass index (BMI)-matched controls.
